LDAP Account Manager (LAM) manages user, group and host accounts in an LDAP directory. LAM runs on any webserver with PHP5 support and connects to your LDAP server unencrypted or via SSL/TLS. Currently LAM supports these account types: Samba 3, Unix, Kolab 2, address book entries, NIS mail aliases and MAC addresses. There is a tree viewer included to allow access to the raw LDAP attributes. You can use templates for account creation and use multiple configuration profiles. LAM is translated to Catalan, Chinese (Traditional + Simplified), Czech, Dutch, English, French, German, Hungarian, Italian, Japanese, Polish, Portuguese, Russian and Spanish. http://www.ldap-account-manager.org/ Copyright (C) 2003 - 2011 Michael Duergner <michael@duergner.com> Roland Gruber <post@rolandgruber.de> Tilo Lutz <tilolutz@gmx.de> Key features: managing user/group/host/domain entries account profiles account creation via file upload multiple configuration profiles LDAP browser schema browser OU editor PDF export for all accounts manage user/group Quota and create home directories Requirements: PHP5 (>= 5.2.4) Openldap (2.0 or greater) A recent web browser that supports CSS2 and JavaScript, at minimum: Firefox 3 Internet Explorer 8 (compatibility mode turned off) Opera 10 The default password to edit the configuration options is "lam".

The LAM development team There are basically two groups of users for LAM: LDAP administrators and support staff: These people administer LDAP entries like user accounts, groups, ... Users: This includes all people who need to manage their own data inside the LDAP directory. E.g. these people edit their contact information with LAM self service (LAM Pro). Therefore, LAM is split into two separate parts, LAM for admins and for users. LAM for admins allows to manage various types of LDAP entries (e.g. users, groups, hosts, ...). It also contains tools like batch upload, account profiles, LDAP schema viewer and an LDAP browser. LAM for users focuses on end users. It provides a self service for the users to edit their personal data (e.g. contact information). The LAM administrator is able to specify what data may be changed by the users. The design is also adaptable to your corporate design. LAM for admins/users is accessible via HTTP(S) by all major web browsers (Firefox, IE, Opera, ...). LAM runtime environment: LAM runs on PHP. Therefore, it is independant of CPU architecture and operating system (OS). You can run LAM on any OS which supports Apache or other PHP compatible web servers. Home directory server: You can manage user home directories and their quotas inside LAM. The home directories may reside on the server where LAM is installed or any remote server. The commands for home directory management are secured by SSH. LAM will use the user name and password of the logged in LAM administrator for authentication. LDAP directory: LAM connects to your LDAP server via standard LDAP protocol. It also supports encrypted connections with SSL and TLS.

LAM has the following requirements to run: Apache webserver (SSL recommended) with PHP module (PHP 5 (>= 5.2.4) with ldap, gettext, xml and optional mcrypt) Some LAM plugins may require additional PHP extensions (you will get a note on the login page if something is missing) Perl (optional, needed only for lamdaemon) OpenLDAP (>2.0) A web browser :-) MCrypt will be used to store your LDAP password encrypted in the session file. See LDAP schema fles for information about used LDAP schema files.

LAM is available as prepackaged version for various platforms.

LAM is part of the official Debian repository. New releases are uploaded to unstable and will be available automatically in testing and the stable releases. You can run apt-get install ldap-account-managerto install LAM on your server. Additionally, you may download the latest LAM Debian packages from the LAM homepage or the Debian package homepage.Installation of the latest packages on Debian Lenny apt-get install javascript-common Download the jquery and jquery-ui packages from here: http://packages.debian.org/squeeze/all/libjs-jquery/download http://packages.debian.org/squeeze/all/libjs-jquery-ui/download Install first jquery and then jquery-ui: dpkg -i libjs-jquery_*.deb dpkg -i libjs-jquery-ui_*.deb Install the LAM package dpkg -i ldap-account-manager_*.deb Install the lamdaemon package (optional) dpkg -i ldap-account-manager-lamdaemon_*.deb

There are RPM packages available on the LAM homepage. The packages can be installed with this commandrpm -i <path to LAM package>

The RPM packages for Suse/Fedora are very generic and should be installable on other RPM-based distributions, too. The Fedora packages use apache:apache as file owner and the Suse ones use wwwrun:www.

LAM is part of the official FreeBSD ports tree. For more details see these pages:FreeBSD-CVS: http://www.freebsd.org/cgi/cvsweb.cgi/ports/sysutils/ldap-account-managerFreshPorts: http://www.freshports.org/sysutils/ldap-account-manager

Please extract the archive with the following command: tar xzf ldap-account-manager-<version>.tar.gz

Copy the files into the html-file scope of the web server. For example /apache/htdocs. Then set the appropriate file permissions: lam/sess: write permission for apache user lam/tmp: write permission for apache user lam/config (with subdirectories): write permission for apache user lam/lib: lamdaemon.pl must be set executable (See also docs/readme.lamdeamon.txt)

Instead of manually copying files you can also use the included configure script to install LAM. Just run these commands in the extracted directory: ./configure make install Options for "./configure": --with-httpd-user=USER USER is the name of your Apache user account (default httpd) --with-httpd-group=GROUP GROUP is the name of your Apache group (default httpd) --with-web-root=DIRECTORY DIRECTORY is the name where LAM should be installed (default /usr/local/lam)

Copy conf/config.cfg_sample to conf/config.cfg and conf/lam.conf_sample to conf/lam.conf. Open the index.html in your web browser: Follow the link "LAM configuration" from the start page to configure LAM. Select "Edit general settings" to setup global settings and to change the master configuration password (default is "lam"). Select "Edit server profiles" to setup your server profiles. There should be the lam profile which you just copied from the sample file. The default password is "lam". Now change the settings to fit for your environment.

LAM runs with PHP5 (>= 5.2.4). Needed changes in your php.ini: memory_limit = 64M If you run PHP with activated Suhosin extension please check your logs for alerts. E.g. LAM requires that "suhosin.post.max_name_length" is increased.

If you want to use a translated version of LAM be sure to install the needed locales. The following table shows the needed locales for the different languages. Language Locale Catalan ca_ES.utf8 Chinese (Simplified) zh_CN.utf8 Chinese (Traditional) zh_TW.utf8 Czech cs_CZ.utf8 Dutch nl_NL.utf8 English no extra locale needed French fr_FR.utf8 German de_DE.utf8 Hungarian hu_HU.utf8 Italian it_IT.utf8 Japanese ja_JP.utf8 Polish pl_PL.utf8 Portuguese pt_BR.utf8 Russian ru_RU.utf8 Spanish es_ES.utf8 You can get a list of all installed locales on your system by executing: locale -a Debian users can add locales with "dpkg-reconfigure locales".

First, you need to make a backup of your existing configuration files. LAM stores all configuration files in the "config" folder. Please backup the following files and copy them after the new version is installed. config/*.conf config/config.cfg config/pdf/*.xml config/profiles/*.xml LAM Pro only: config/selfService/*.* config/passwordMailTemplate.txt Second, uninstall your current LAM (Pro) installation. Third, install the new LAM (Pro) release. Skip the part about setting up LAM configuration files. Finally, restore your configuration files from the backup. Copy all files from the backup folder to the config folder in your LAM Pro installation. Do not simply replace the folder because the new LAM (Pro) release might include additional files in this folder. Overwrite any existing files with your backup files. Now open your webbrowser and point it to the LAM login page. All your settings should be migrated. Please check also the version specific instructions. They might include additional actions.

If you use custom images for the PDF export then these images need to be 5 times bigger than before (e.g. 250x250px instead of 50x50px). This allows to use images with higher resolution.

No changes.

LAM supported to set a list of valid workstations on the "Personal" page. This required to change the LDAP schema. Since 3.1.0 this is replaced by the new "Hosts" module for users. Lamdaemon: The sudo entry needs to be changed to ".../lamdaemon.pl *".

No changes.

LAM Pro: There is now a separate account type for group of (unique) names. Please edit your server profiles to activate the new account type.

No changes.

If you used the prepackaged installation packages then remove the ldap-account-manager and ldap-account-manager-lamdaemon packages. Otherwise, remove the folder where you installed LAM via configure or by copying the files.

After you installed LAM you can configure it to fit your needs. The complete configuration can be done inside the application. There is no need to edit configuration files. Please point you browser to the location where you installed LAM. E.g. for Debian/RPM this is http://yourServer/lam. If you installed LAM via the tar.gz then this may vary. You should see the following page: If you see an error message then you might need to install an additional PHP extension. Please follow the instructions and reload the page afterwards. Now you are ready to configure LAM. Click on the "LAM configuration" link to proceed. Here you can change LAM's general settings, setup server profiles for your LDAP server(s) and configure the self service (LAM Pro). You should start with the general settings and then setup a server profile.

After selecting "Edit general settings" you will need to enter the master configuration password. The default password for new installations is "lam". Now you can edit the general settings.

Here you can set a time period after which inactive sessions are automatically invalidated. The selected value represents minutes of inactivity. You may also set a list of IP addresses which are allowed to access LAM. The IPs can be specified as full IP (e.g. 123.123.123.123) or with the "*" wildcard (e.g. 123.123.123.*). Users which try to access LAM via an untrusted IP only get blank pages.

This allows you to specify a central password policy for LAM. The policy is valid for all password fields inside LAM admin (excluding tree view) and LAM self service. Configuration passwords do not need to follow this policy. You can set the minimum password length and also the complexity of the passwords.

LAM can log events (e.g. user logins). You can use system logging (syslog for Unix, event viewer for Windows) or log to a separate file. Please note that LAM may log sensitive data (e.g. passwords) at log level "Debug". Production system should be set to "Warning" or "Error".

If you would like to change the master configuration password then enter a new password here.

The server profiles store information about your LDAP server (e.g. host name) and what kind of accounts (e.g. users and groups) you would like to manage. There is no limit on the number of server profiles. See the typical scenarios about how to structure your server profiles.

Select "Manage server profiles" to open the profile management page. Here you can create, rename and delete server profiles. The passwords of your server profiles can also be reset. You may also specify the default server profile. This is the server profile which is preselected at the login page. It also specifies the language of the login and configuration pages. You can create a new server profile by simply entering its name and password. After you created a new profile you can go back to the profile login and edit your new server profile. All operations on the profile management page require that you authenticate yourself with the configuration master password.

Please select you server profile and enter its password to edit a server profile. Each server profile contains the following information: General settings: general settings about your LDAP server (e.g. host name and security settings) Account types: list of account types (e.g. users and groups) that you would like to manage and type specific settings (e.g. LDAP suffix) Modules: list of modules which define what account aspects (e.g. Unix, Samba, Kolab) you would like to manage Module settings: settings which are specific for the selected account modules on the page before

Here you can specify the LDAP server and some security settings. The server address of your LDAP server can be a DNS name or an IP address. Use ldap:// for unencrypted LDAP connections or TLS encrypted connections. LDAP+SSL (LDAPS) encrypted connections are specified with ldaps://. The port value is optional. TLS cannot be combined with ldaps://. LAM includes an LDAP browser which allows direct modification of LDAP entries. If you would like to use it then enter the LDAP suffix at "Tree suffix". The search limit is used to reduce the number of search results which are returned by your LDAP server. The access level specifies if LAM should allow to modify LDAP entries. This feature is only available in LAM Pro. LAM non-Pro releases use write access. See this page for details on the different access levels. LAM is translated to many different languages. Here you can select the default language for this server profile. The language setting may be overriden at the LAM login page. LAM can manage user home directories and quotas with an external script. You can specify the home directory server and where the script is located. The default rights for new home directories can be set, too. LAM supports two methods for login. You may either specify a fixed list of LDAP DNs or let LAM search for the DN in your directory. E.g. if a user logs in with the user name "joe" then LAM will do an LDAP search for this user name. When it finds a matching DN then it will use this to authenticate the user. The wildcard "%USER%" will be replaced by "joe" in this example. This way you can provide login by user name, email address or other LDAP attributes. You may also change the password of this server profile.

LAM supports to manage various types of LDAP entries (e.g. users, groups, DHCP entries, ...). On this page you can select which types of entries you want to manage with LAM. The section at the top shows a list of possible types. You can activate them by simply clicking on the plus sign next to it. Each account type has the following options: LDAP suffix: the LDAP suffix where entries of this type should be managed List attributes: a list of attributes which are shown in the account lists On the next page you can specify in detail what extensions should be enabled for each account type.

The modules specify the active extensions for each account type. E.g. here you can setup if your user entries should be address book entries only or also support Unix or Samba. Each account type needs a so called "base module". This is the basement for all LDAP entries of this type. Usually, it provides the structural object class for the LDAP entries. There must be exactly one active base module for each account type. Furthermore, there may be any number of additional active account modules. E.g. you may select "Personal" as base module and Unix + Samba as additional modules.

Depending on the activated account modules there may be additional configuration options available. They can be found on the "Module settings" tab. E.g. the Personal account module allows to hide several input fields and the Unix module requires to specify ranges for UID numbers.

This is a list of typical scenarios how your LDAP environment may look like and how to structure the server profiles for it.

This is the easiest and most common scenario. You want to manage a single LDAP server and there is only one or a few admins. In this case just create one server profile and you are done. The admins may be either specified as a fixed list or by using an LDAP search at login time.

Large organisations may have one big LDAP directory for all user/group accounts. But the users are managed by different groups of admins (e.g. departments, locations, subsidiaries, ...). The users are typically divided into organisational units in the LDAP tree. Admins may only manage the users in their part of the tree. In this situation it is recommended to create one server profile for each admin group (e.g. department). Setup the LDAP suffixes in the server profiles to point to the needed organisational units. E.g. use ou=people,ou=department1,dc=company,dc=com or ou=department1,ou=people,dc=company,dc=com as LDAP suffix for users. Do the same for groups, hosts, ... This way each admin group will only see its own users. You may want to use LDAP search for the LAM login in this scenario. This will prevent that you need to update a server profile if the number of admins changes. Attention: LAM's feature to automatically find free UIDs/GIDs for new users/groups will not work in this case. LAM uses the user/group suffix to search for already assigned UIDs/GIDs. As an alternative you can specify different UID/GID ranges for each department. Then the UIDs/GIDs will stay unique for the whole directory.

You can manage as many LDAP servers with LAM as you wish. This scenario is similar to the advanced scenario above. Just create one server profile for each LDAP server.

LAM was tested to work with 10 000 users. If you have a lot more users then you have basically two options. Divide your LDAP tree in organisational units: This is usually the best performing option. Put your accounts in several organisational units and setup LAM as in the advanced scenario above. Increase memory limit: Increase the memory_limit parameter in your php.ini. This will allow LAM to read more entries. But this will slow down the response times of LAM.

This chapter will give you instructions how to manage the different LDAP entries in your directory. Please note that not all account types are manageable with the free LAM release. LAM Pro provides some more account types and modules to support additional LDAP object classes. Additional types: Group of names Aliases NIS objects Sudo roles Additional modules: Group of names (groupOfNames) Group of unique names (groupOfUniqueNames) Unix (rfc2307bisPosixGroup) Alias (aliasEntry) User name (uidObject) NIS object (nisObject) Custom scripts (customScripts) Sudo role (sudoRole) Basic page layout: After the login LAM will present you its main page. It consists of a header part which is equal for all pages and the content area which covers most the of the page. The header part includes the links to manage all account types (e.g. users and groups) and open the tree view (LDAP browser). There is also the logout link and a tools entry. When you login the you will see an account listing in the content area. Here you can create, delete and modify accounts. Use the action buttons at the left or double click on an entry to edit it. The suffix selection box allows you to list only the accounts which are located in a subtree of your LDAP directory. You can change the number of shown entries per page with "Change settings". Depending on the account type there may be additional settings. E.g. the user list can convert group numbers to group names. When you select to edit an entry then LAM will show all its data on a tabbed view. There is one tab for each functional part of the account. You can set default values by loading an account profile.

This module is the most common basis for user accounts in LAM. You can use it stand-alone to manage address book entries or in combination with Unix, Samba or other modules. The Personal module provides support for managing various personal data of your users including mail addresses and telephone numbers. You can also add photos of your users. If you do not need to manage all attributes then you can deactivate them in your server profile. Attribute name Name inside LAM businessCategory Business category carLicense Car license cn/commonName Common name departmentNumber Department(s) description Description employeeType Employee type facsimileTelephoneNumber/fax Fax number givenName/gn First name homePhone Home telephone number jpegPhoto Photo l Location mail/rfc822Mailbox Email address manager Manager mobile/mobileTelephoneNumber Mobile number physicalDeliveryOfficeName Office name postalAddress Postal address postalCode Postal code postOfficeBox Post office box roomNumber Room number sn/surname Last name st State street/streetAddress Street telephoneNumber Telephone number title Job title uid/userid User name userPassword Password

The Unix module manages Unix user accounts including group memberships.

LAM supports the management of the LDAP substitution of /etc/shadow. Here you can setup password policies for your Unix accounts and also view the last password change of a user.

You can specify a list of valid host names where the user may login. If you add the value "*" then the user may login to any host. This can be further restricted by adding explicit deny entries which are prefixed with "!" (e.g. "!hr_server"). Please note that your PAM settings need to support host restrictions.

LAM supports full Samba 3 user management including logon hours and terminal server options.

You can manage file system quotas with LAM. This requires to setup lamdaemon. File system quotas are not stored inside LAM but managed directly on the specified servers.

This module supports to manage Kolab accounts with LAM. E.g. you can set the user's mail quota and define invitation policies. Please enter an email address at the Personal page and set a Unix password first. Both are required that Kolab accepts the accounts. Kolab users should not be directly deleted with LAM. You can mark an account for deletion which then is done by the Kolab server itself. This makes sure that the mailbox etc. is also deleted.

You may manage several attributes of phpGroupWare users inside LAM. This includes the expiration date and account status. You may also check when the user logged in the last time and from where.

LAM supports Asterisk accounts, too. See the Asterisk section for details.

EDU person accounts are mainly used in university networks. You can specify the principal name, nick names and much more.

OpenLDAP supports the ppolicy overlay to manage password policies for LDAP entries. LAM Pro supports managing the policies and assigning them to user accounts. Please add the account type "Password policies" to your LAM server profile and activate the "Password policy" module for the user type. You can assign any password policy which is found in the LDAP suffix of the "Password policies" type. When you set the policy to "default" then OpenLDAP will use the default policy as defined in your slapd.conf file.

LAM supports to manage mail routing for user accounts. You can specify a routing address, the mail server and a number of local addresses to route. This feature can be activated by adding the "Mail routing" module to the user account type in your server profile.

You can manage your public keys for SSH in LAM if you installed the LPK patch for SSH. Activate the "SSH public key" module for users in the server profile and you can add keys to your user entries.

LAM may create and delete mailboxes on an IMAP server for your user accounts. You will need an IMAP server that supports either SSL or TLS for this feature. To activate the mailbox management module please add the "Mailbox (imapAccess)" module for the type user in your LAM server profile: Now configure the module on the tab "Module settings". Here you can specify the IMAP server name, encryption options, the authentication for the IMAP connection and the valid mail domains. LAM can use either your LAM login password for the IMAP connection or display a dialog where you need to enter the password. The mail domains specify for which accounts mailboxes may be created/deleted. E.g. if you enter "lam-demo.org" then mailboxes can be managed for "user@lam-demo.org" but not for "user@example.com". You need to install the SSL certificate of the CA that signed your server certificate. This is usually done by installing the certificate in /etc/ssl/certs. Different Linux distributions may offer different ways to do this. For Debian please copy the certificate in "/usr/local/share/ca-certificates" and run "update-ca-certificates" as root. It is not recommended to disable the validation of IMAP server certificates. When you edit an user account then you will now see the tab "Mailbox". Here you can create/delete the mailbox for this user.

This is a very simple module to manage accounts based on the object class "account". Usually, this is used for host accounts only. Please pay attention that users based on the "account" object class cannot have contact information (e.g. telephone number) as with "inetOrgPerson". You can enter a user/host name and a description for your accounts.

This module is used to manage Unix group entries. This is the default module to manage Unix groups and uses the nis.schema. Suse users who use the rfc2307bis.schema need to use LAM Pro.

Some applications (e.g. Suse Linux) use the rfc2307bis schema for Unix accounts instead of the nis schema. In this case group accounts are based on the object class groupOf(Unique)Names. The object class is auxiliary in this case. LAM Pro supports these groups with a special account module: rfc2307bisPosixGroup Use this module only if your system depends on the rfc2307bis schema. The module can be selected in the LAM configuration.

LAM supports managing Samba 3 groups. You can set special group types and also create Windows predefined groups like "Domain admins".

LAM can add and remove the phpGroupWare extension for group accounts. There are no additional attributes that may be managed.

You can manage file system quotas with LAM. This requires to setup lamdaemon. File system quotas are not stored inside LAM but managed directly on the specified servers.

Please see the description here.

The device object class allows to manage general information about all sorts of devices (e.g. computers, network hardware, ...). You can enter the serial number, location and a describing text. It is also possible to specify the owner of the device.

You can manage Samba 3 host entries by adding the Unix and Samba 3 account modules.

You can manage the IP addresses of host accounts with the ipHost module. It manages the following information: IP addresses (IPv4/IPv6) location of the host manager: the person who is responsible for the host You can activate this extension by adding the module ipHost to the list of active host modules.

Hosts can have an unlimited number of MAC addresses. To enable this feature just add the "MAC address" module to the host account type.

Samba 3 stores information about its domain settings inside LDAP. This includes the domain name, its SID and some policies. You can manage all these attributes with LAM. Please activate the account type "Samba domains" in your LAM server profile. Please notice that Samba by default uses the LDAP root for domain objects (e.g. dc=example,dc=com). This will add a new tab to LAM where you can manage domain information. The domain name, SID and RID base can only be specified for new domains and are not changeable via LAM at a later time. You may setup several password policies for your Samba domains and also some RID options that influence the creation of SIDs for users/groups/hosts.

These classes can be used to represent group relations. Since they allow DNs as members you can also use them to represent nested groups. Activate the account type "Group of names" in your LAM server profile to use these account modules. Group of (unique) names have four basic attributes: Name: a unique name for the group Description: optional description Owner: the account which owns this group (optional) Members: the members of the group (at least one is required) You can add any accounts as members. This includes other groups which leads to nested groups.

LAM includes large support for Asterisk. You can add Asterisk extensions (including voicemail) to your users and also manage Asterisk extensions. The Asterisk support for users can be added by selecting the Asterisk and Asterisk voicemail modules for users in your LAM server profile. This will add the following tabs to your user accounts. If you also want to manage Asterisk extensions then simply add the account type "Asterisk extensions" and its module to your server profile.

Zarafa is an OpenSource collaboration software. LAM pro provides support to manage Zarafa server entries, users and groups. LAM covers all settings for these types including resource and quota settings.

To enable Zarafa support in LAM Pro please activate the Zarafa modules for the Users, Groups and Hosts account types in you server profile: You can configure which parts of the Zarafa user options should be enabled. E.g. if you do not want to manage quotas per user then you can hide these options on the tab "Module settings". "Send as" attribute: Here you can specify how "Send as" privileges should be managed. LAM supports "uid" and "dn". If you select "uid" the LAM will store user names in the zarafaSendAsPrivilege attribute. This way you are restricted to specify user accounts as "Send as" allowed. You can also set this option to "dn" and LAM will store DNs in the zarafaSendAsPrivilege attribute. In this case you may specify users and groups as "Send as" allowed. Examples for your Zarafa ldap.cfg: "Send as" attribute: dn ldap_user_sendas_attribute_type = dn "Send as" attribute: uid ldap_user_sendas_attribute_type = text ldap_user_sendas_relation_attribute = uid

This is an example of the user edit page with all possible settings. This includes email settings, quotas and some options (e.g. hide from address book). You can also set the resource type and capacity for meeting rooms and equipment. The Zarafa extension can be added and removed at any time for every user.

This is the edit page for groups. You can enter an email address and additional aliases for your groups. It is also possible to specify options (e.g. hide from address book). The extension can be added/removed dynamically.

The Zarafa extension for host accounts allows to set the connection ports and file path. You can add/remove the extension at any time.

You can mange your DHCP server with LAM. It supports to manage subnets, fixed IP entries, IP ranges and DDNS. The DHCP can be activated by adding the account type DHCP to your server profile. Please also add the DHCP modules. LAM requires that you use an LDAP entry with the object class "dhcpServer" as suffix for this account type. You can also change the settings of your DHCP server entry: You can easily create new subnet entries. It is also possible to specify a list of fixed IPs. IP ranges may be specified. If you activated DDNS in the server entry then you may also specify the DDNS settings for this subnet.

Some applications use the object class "alias" to link LDAP entries to other parts of the LDAP tree. Activate the account type "Aliases" in your LAM server profile to use this account type. Currently, only user accounts can be aliased with the "uidObject" object class.

You can manage mail aliases (e.g. for NIS) inside LAM. This can be used to replace local /etc/aliases files with LDAP. All accounts of this type are based on the "nisMailAlias" object class and may have "cn" and "rfc822MailMember" attributes. To activate this type please add "Mail aliases" in your LAM server profile: The mail aliases will appear as separate tab inside LAM. You may then manage the aliases with their names and recipient addresses.

LAM supports to define NIS netgroups. You can use them e.g. to restrict SSH access to your machines. Add the NIS net group account type and its module to your server profile. Then you can manage net groups in LAM. Net groups may contain other net groups as child groups. You can either insert the host/user names manually or print the search buttons next to the input fields to find existing entries in your directory.

You can manage NIS objects with LAM Pro. This allows you define network mount points in LDAP. Add the NIS objects type to your LAM configuration and then the NIS objects module. This will add the NIS objects tab to LAM.

OpenLDAP supports the ppolicy overlay to manage password policies for LDAP entries. This allows you to set password policies which are independent from your applications. The policies are managed internally by the LDAP server. You can manage these policies with LAM Pro with the account type "Password policies". You will need to add the ppolicy schema to your OpenLDAP configuration and activate the ppolicy overlay module in slapd.conf to use this feature.

LAM Pro allows you to execute scripts whenever an account is created, modified or deleted. This can be useful to automate processes which needed manual work afterwards (e.g. sending your user a welcome mail or register a mailbox). To activate this feature please add the "Custom scripts" module to all needed account types on the configuration pages. You can specify multiple scripts for each action type (e.g. modify) and account type (e.g. user). The scripts need to be located on the filesystem of your webserver and will be executed in its user environment. E.g. if you webserver runs as user www-data with the group www-data then the custom scripts will be run under this user with his rights. The output of the scripts will be shown in LAM. You can specify the scripts on the LAM configuration pages. Syntax: Please enter one script per line. Each line has the following format: <account type> <action> <script> E.g.: user preModify /usr/bin/myCustomScript -u $uid$ Account types: You can setup scripts for all available account types (e.g. user, group, host, ...). Please see the help on the configuration page about your current active account types. Actions: Action name Description preCreate executed before creating a new account (cancels operation if a script returns an exit code > 0) postCreate executed after creating a new account preModify executed before the account is modified (cancels operation if a script returns an exit code > 0) postModify executed after an account was modified preDelete executed before an account was modified (cancels operation if a script returns an exit code > 0) postDelete executed after an account was modified Script: You can execute any script which is located on the filesystem of your webserver. The path may be absolute or relative to the PATH-variable of the environment of your webserver process. It is also possible to add commandline arguments to your scripts. Additionally, LAM will resolve wildcards to LDAP attributes. If your script includes an wildcard in the format $ATTRIBUTE$ then LAM will replace it with the attribute value of the current LDAP entry. The values of multi-value attributes are separated by commas. E.g. if you create an account with the attribute "uid" and value "steve" then LAM will resolve "$uid$" to "steve". Output may contain HTML: If your scripts generate HTML output then activate this option. Hide command in messages: You may want to prevent that your users see the executed commands. In this case activating this option will only show the command output but not the command itself. You can see a preview of the commands which will be executed on the "Custom scripts" tab.

You can manage your sudo roles in LDAP if you have installed the sudo-ldap package or compiled sudo with LDAP support. To activate sudo management in LAM Pro edit your server profile and add the type "Sudo roles". The sudo roles in LDAP work similar to those in /etc/sudoers. You can specify who may run which commands as which user. It is also possible to specify options like NOPASSWD.

The tree view provides a raw view on your LDAP directory. This feature is for people who are experienced with LDAP and need special functionality which the LAM account modules not provide. E.g. if you want to add a special object class to an account or edit attributes ignoring LAM's syntax checks. There are also some special functions available: Export: This allows you to export entries to a file (e.g. LDIF or CSV format). Show internal attributes: Shows internal attributes of the current entry. This includes information about the creator and creation time of the entry.

Here is a list of typical usage scenarios and what account types and modules you need to configure. Address book entries: Account types: Users (Personal) Unix accounts: Account types: Users (Personal + Unix) Groups (Unix (posixGroup)) Suse users may need to use Group (Group of names + Unix (rfc2307bisPosixGroup)) because of Suse's special LDAP schema. Samba accounts: Account types: Users (Personal + User + Samba 3) Groups (Unix + Samba 3) Hosts (Account + Unix + Samba 3) Samba domains (Samba domain) Asterisk: Account types: Users (Personal + Asterisk) Asterisk extensions (Asterisk extension) phpGroupWare: Account types: Users (Personal + Unix + phpGroupWare) Groups (Unix + phpGroupWare) Zarafa: Account types: Users (Personal + Unix + Zarafa) Groups (Unix + Zarafa) Hosts (Device + Zarafa + IP Address)

The account profiles are templates for your accounts. Here you can specify default values which can then be loaded when you create accounts. You may also load a template for an existing account to reset it to default values. When you create a new account then LAM will always load the profile named "default". This account profile can include default values for all your accounts.

When you need to create lots of accounts then you can use LAM's file upload to create them. LAM will read a CSV formatted file and create the related LDAP entries. Please check the data in you CSV file carefully. LAM will do less checks for the file upload than for single account creation. At the first page please select the account type and what extensions should be activated. The next page shows all available options for the file upload. You will also find a sample CSV file which can be used as template for your CSV file. All red options are required columns in the file. You need to specify a value for each account. When you upload the CSV file then LAM first does some checks on this file. This includes syntax checks and if all required data was entered. No changes in the LDAP directory are done at this time. If the checks were successful then LAM will ask again if you want to create the accounts. You will also have the chance to check the upload by viewing the changes in LDIF format.

This is a simple editor to add/delete organisational units in your LDAP tree. This way you can structure the accounts.

All accounts in LAM may be exported as PDF files. You can specify the page structure and displayed information by editing the PDF profiles. When you export accounts to PDF then each account will get its own page inside the PDF. There is a headline on each page where you can show a page title. You may also add a logo to each page. To add more possible logos simply copy the images to config/pdf/logos. The main part is structured into sections of information. Each section has a title. This can either be static text or the value of an attribute. You may also insert a static text block as section. Sections can be moved by using the arrows next to the section title. Each section can contain multiple fields which usually represent LDAP attributes. You can simply add new fields by selecting the field name and its position. Then use the arrows to move the field inside the section.

Here you browse the schema of your LDAP server. You can view what object classes, attributes, syntaxes and matching rules are available. This is useful if you need to check if a certain object class is available.

This shows some basic information about your LDAP server.

This allows you to check if your LDAP schema is compatible with LAM and to find possible problems.

LAM provides an external script to manage home directories and quotas. You can test here if everything is setup correctly.

This will test if your LDAP schema supports all object classes and attributes of the active LAM modules. If you get a message that something is missing please check that you installed all required schemas. If you get error messages about object class violations then this test can tell you what is missing.

You can define different access levels for each profile to allow or disallow write access. The password reset page helps your deskside support staff to reset user passwords.

There are three access levels: Write access (default) There are no restrictions. LAM admin users can manage account, create profiles and set passwords. Change passwords Similar to "Read only" except that the password reset page is available. Read only No write access to the LDAP database is allowed. It is also impossible to manage account and PDF profiles. Accounts may be viewed but no changes can be saved. The access level can be set on the server configuration page:

This special page allows your deskside support staff to reset the Unix and Samba passwords of your users. If you set the access level to "Change passwords" then LAM will not allow any changes to the LDAP database except password changes via this page. The account pages will be still available in read-only mode. You can open the password reset page by clicking on the key symbol on each user account: There are three different options to set a new password: set random password and display it on screen This will set the user's password to a random value. The password will be 11 characters long with a random combination of letters, digits and ".-_". You may want to use this method to tell users their new passwords via phone. set random password and mail it to user If the user account has set the mail attribute then LAM can send your user a mail with the new password. You can change the mail template to fit your needs. See the help link for further details. Using this method will prevent that your support staff knows the new password. set specific password Here you can specify your own password. LAM will display contact information about the user like the user's name, email address and telephone number. This will help your deskside support to easily contact your users. Options: Depending on the account there may be additional options available. Sync Samba NT/LM password with Unix password: If a user account has Samba passwords set then LAM will offer to synchronize the passwords. Unlock Samba account: Locked Samba accounts can be unlocked with the password change. Update Samba password timestamps: This will set the timestamps when the password was changed (sambaPwdLastSet), may be changed again (sambaPwdCanChange) and must be changed again (sambaPwdMustChange). Only existing attributes are updated. No new attributes are added.

By default only a few administrative users have write access to the LDAP database. Before your users may change their settings you must allow them to change their LDAP data. This can be done by adding an ACL to your slapd.conf which looks like this: access to attrs=mail,sn,givenName,telephoneNumber,mobile,facsimileTelephoneNumber,street,postalAddress,postOfficeBox,postalCode,userPassword,shadowLastChange by self write If you do not want them to change all attributes then reduce the list to fit your needs. Some modules may require additional LDAP attributes. Usually, the slapd.conf file is located in /etc/ldap or /etc/openldap.

There exist many LDAP implementations. If you do not use OpenLDAP you need to write your own ACLs. Please check the manual of your LDAP server for instructions.

A self service profile defines what input fields your users see and some other general settings like the login caption. When you go to the LAM configuration page you will see the self service link at the bottom. This will lead you to the self service configuration pages Now we need to create a new self service profile. Click on the link to manage the self service profiles. Specify a name for the new profile and enter your master configuration password (default is "lam") to save the profile. Now go back to the profile login and enter your master configuration password to edit your new profile.

On top of the page you see the link to the user login page. Copy this link address and give it to your users. Below the link you can specify several options. Server address The address of your LDAP server LDAP suffix The part of the LDAP tree where LAM should search for users LDAP user + password The DN and password which is used to search for users in the LDAP database. It is sufficient if this DN has only read rights. If you leave these fields empty LAM will try to connect anonymously. LDAP search attribute Here you can specify if your users can login with user name + password, email + password or other attributes. Login attribute label This is the description for the LDAP search attribute. Set it to something which your users are familiar with. Login caption This text is displayed at the login page. You can input HTML, too. Main page caption This text is displayed at self service main page where your users change their data. You can input HTML, too. Page header This HTML code will be placed on top of all self service pages. E.g. you can use this to place your custom logo. Any HTML code is permitted. Additional CSS links Here you can specify additional CSS links to change the layout of the self service pages. This is useful to adapt them to your corporate design. Please enter one link per line. On the bottom you can specify what input fields your users can see. It is also possible to group several input fields.

LAM Pro allows you to integrate customs CSS style definitions and design the header of all self service pages. This way you can integrate you own logo and use your company's colors.

The default LAM Pro header includes a logo and a horizontal line. You can enter any HTML code here. It will be included in the self services pages after the body tag.

Usually, companies have regulations about their corporate design and use common CSS files. This assures a common appearance of all intranet pages (e.g. colors and fonts). To include additional CSS files just use the following setting for this task. The additional CSS links will be added after LAM Pro's default CSS link. This way you can overwrite LAM Pro's style.

Here is a list of needed LDAP schema files for the different LAM modules. For OpenLDAP we also provide a source where you can get the files. Account type Object class(es) Schema name Source Notes Unix accounts posixAccount, shadowAccount, hostObject, posixGroup nis.schema, rfc2307bis.schema, ldapns.schema (hostObject) Part of OpenLDAP installation, part of libpam-ldap (ldapns.schema) The rfc2307bis.schema is only supported by LAM Pro. Use the nis.schema if you do not want to upgrade to LAM Pro. Address book entries inetOrgPerson inetorgperson.schema Part of OpenLDAP installation Samba 3 accounts sambaSamAccount, sambaGroupMapping, sambaDomain samba.schema Part of Samba tarball (examples/LDAP/samba.schema) Kolab 2 users kolabUser kolab2.schema, rfc2739.schema Part of Kolab 2 installation Asterisk (extension) AsteriskSIPUser, AsteriskExtension asterisk.schema Part of Asterisk installation Mail routing inetLocalMailRecipient misc.schema Part of OpenLDAP installation Hosts hostObject, device ldapns.schema Part of libpam-ldap installation The device object class is only available in LAM Pro.

LAM supports a two level authorization system for its configuration. Therefore, there are two types of configuration passwords: master configuration password: needed to change general settings, create/delete server profiles and self service profiles server profile password: used to change the settings of a server profile (e.g. LDAP server and account types to manage) The master configuration password can be used to reset a server profile password. Each server profile has its own profile password. Both password types are stored as hash values in the configuration files for enhanced security.

The data which is transfered between you and LAM is very sensitive. Please always use SSL encrypted connections between LAM and your browser to protect yourself against network sniffers.

SSL will be used if you use ldaps://servername in your configuration profile. TLS can be activated with the "Activate TLS" option. You will need to setup ldap.conf to trust your server certificate. Some installations use /etc/ldap.conf and some use /etc/ldap/ldap.conf. It is a good idea to symlink /etc/ldap.conf to /etc/ldap/ldap.conf. Specify the server CA certificate with the following option: TLS_CACERT /etc/ldap/ca/myCA/cacert.pem This needs to be the public part of the signing certificate authority. See "man ldap.conf" for additional options.

If your server is chrooted and you have no access to /dev/random or /dev/urandom this can be a security risk. LAM stores your LDAP password encrypted in the session. LAM uses rand() to generate the key if /dev/random and /dev/urandom are not accessible. Therefore the key can be easily guessed. An attaker needs read access to the session file (e.g. by another Apache instance) to exploit this.

You have to install the MCrypt extension for PHP to enable encryption. Your LDAP password is stored encrypted in the session file. The key and IV to decrypt it are stored in two cookies. We use MCrypt/AES to encrypt the password. All data that was read from LDAP and needs to be stored in the session file is also encrypted.

LAM includes several .htaccess files to protect your configuration files and temporary data. Apache is often configured to not use .htaccess files by default. Therefore, please check your Apache configuration and change the override setting to: AllowOverride All If you are experienced in configuring Apache then you can also copy the security settings from the .htaccess files to your main Apache configuration. If possible, you should not rely on .htaccess files but also move the config and sess directory to a place outside of your WWW root. You can put a symbolic link in the LAM directory so that LAM finds the configuration/session files. Security sensitive directories: config: Contains your LAM configuration and account profiles LAM configuration passwords (SSHA hashed) default values for new accounts directory must be accessibly by Apache but needs not to be accessible by the browser sess: PHP session files LAM admin password in clear text or MCrypt encrypted cached LDAP entries in clear text or MCrypt encrypted directory must be accessibly by Apache but needs not to be accessible by the browser tmp: temporary files PDF documents which may also include passwords images of your users directory contents must be accessible by browser but directory itself needs not to be browseable

Some basic hints to configure the OpenLDAP server: Size limit: OpenLDAP allows by default 500 return values per search, if you have more users/groups/hosts change this in slapd.conf: e.g. "sizelimit 10000" or "sizelimit -1" for unlimited return values. Indices: Indices will improve the performance when searching for entries in the LDAP directory. The following indices are recommended: index objectClass eq index default sub index uidNumber eq index gidNumber eq index memberUid eq index cn,sn,uid,displayName pres,sub,eq # Samba 3.x index sambaSID eq index sambaPrimaryGroupSID eq index sambaDomainName eq Lamdaemon.pl is used to modify quota and home directories on a remote or local host via SSH. If you want wo use it you have to set up the following things to get it to work:

Set the remote or local host in the configuration (e.g. 127.0.0.1) Path to lamdaemon.pl, e.g. /srv/www/htdocs/lam/lib/lamdaemon.pl If you installed a Debian or RPM package then the script may be located at /usr/share/ldap-account-manager/lib or /var/www/html/lam/lib. Your LAM admin user must be a valid Unix account. It needs to have the object class "posixAccount" and an attribute "uid". This account must be accepted by the SSH daemon of your home directory server. Do not create a second local account but change your system to accept LDAP users. You can use LAM to add the Unix account part to your admin user.

The perl script has to run as root. Therefore we need a wrapper, sudo. Edit /etc/sudoers on host where homedirs or quotas should be used and add the following line: $admin All= NOPASSWD: $path_to_lamdaemon * $admin is the admin user from LAM (must be a valid Unix account) and $path_to_lamdaemon is the path to lamdaemon.pl. Example: myAdmin ALL= NOPASSWD: /srv/www/htdocs/lam/lib/lamdaemon.pl * You might need to run the sudo command once manually to init sudo. The command "sudo -l" will show all possible sudo commands of the current user.

We need an extra Perl module - Quota. To install it, run: perl -MCPAN -e shell install Quota If your Perl executable is not located in /usr/bin/perl you will have to edit the path in the first line of lamdaemon.pl. If you have problems compiling the Perl modules try installing a newer release of your GCC compiler and the "make" application. Several Linux distributions already include a quota package for Perl.

Your SSH daemon must offer the password authentication method. To activate it just use this configuration option in /etc/ssh/sshd_config: PasswordAuthentication yes

If you have problems managing quotas and home directories then these points might help: There is a test page for lamdaemon: Login to LAM and open Tools -> Tests -> Lamdaemon test Check /var/log/auth.log or its equivalent on your system. This file contains messages about all logins. If the ssh login failed then you will find a description about the reason here. Set sshd in debug mode. In /etc/ssh/sshd_conf add these lines: SyslogFacility AUTH LogLevel DEBUG3 Now check /var/log/syslog for messages from sshd. Update Openssh. A Suse Linux user reported that upgrading Openssh solved the problem.

Here are some notes on managing Kolab accounts with LAM:

The mailbox server cannot be changed after the account has been saved. Please make sure that the value is correct. The email address ("Personal" page) must match your Kolab domain, otherwise the account will not work.

If you want to cleanly delete accounts use the "Mark for deletion" button on the Kolab subpage of an account. This will also remove the user's mailbox. If you delete the account from the account list (which is standard for LAM accounts) then no cleanup actions are made.

The Kolab GUI has some restrictions that LAM does not have. Please pay attention to the following restrictions: Common name in LAM The common name must have the format "<first name> <last name>". You can leave the field empty in LAM and it will automatically fill in the correct value. Changing first/last name in Kolab GUI Do not change the first/last name of your users in the Kolab GUI! The GUI will change the common name which leads to an LDAP object class violation. This is caused by a bug in the Kolab GUI.

If you upgrade existing non-Kolab accounts please make sure that the account has an Unix password.

You can install LAM in the directory "/kolab/var/kolab/www" which is the root directory for Apache. The PHP installation already includes all required packages.
